This invention has for its object to proto prevent the accumulation of moisture, vide a novel and highly efficient preparation water, mist, snow and sleet upon the glass I for application to window panes, windor other surface to which the preparation is shields, and the other glass or hard enamel applied. The sulphur, denatured alcohol and surfaces, for the purpose of preventing the table salt are used to reduce the composition accumulation of steam, rain, snow, mist, frost to the desired consistency and to lower the or ice upon such surfaces. freezing point of the preparation as well as Another object of the invention is to proto enhance its property of loosening snow vide a composition in lirl guid form which may or sleet accumulation upon surfaces to which 16 be applied to glass or li e surfaces for facilthe preparation may be applied.
